Inelastic processes in K+-He collisions in energy range 0.7–10 keV

Imaging resonances in low-energy NO-He inelastic collisions.

In molecular collisions, resonances occur at specific energies at which the colliding particles temporarily form quasibound complexes, resulting in rapid variations in the energy dependence of scattering cross sections. Experimentally, it has proven challenging to observe such scattering resonances, especially in differential cross sections. We report the observation of resonance fingerprints i...

Mutual Ionization in 200 keV H - He Collisions

By now many experimental data on fully differential cross sections (FDCS) exist for single target ionization covering a broad range of different collision systems. At this stage it therefore seems reasonable to turn to somewhat more complex ionization processes and to fully exploit the opportunities provided by heavy projectiles, in order to advance our understanding of collision-induced few-pa...

Probing Scattering Resonances in (Ultra)Cold Inelastic NO-He Collisions.

We theoretically study inelastic collisions between NO radicals and He atoms at low collision energies, focusing on the occurrence of scattering resonances. We specifically investigate de-excitation of rotationally excited NO radicals (X (2)Π1/2, v = 0, j = 3/2, f) at collision energies ranging from 10(-3) to 20 cm(-1) and compute integral and differential cross sections using quantum mechanica...

Angular and energy distribution of electrons from 15- to 150-keV H0+He collisions

Water-molecule fragmentation induced by charge exchange in slow collisions with He+ and He2+ ions in the keV-energy region

Charge exchange and fragmentation in the collision systems He+H2O and He +H2O are theoretically investigated at projectile energies of a few keV. The calculations are based on the electron nuclear dynamics END method which solves the time-dependent Schrödinger equation. Total and differential cross sections for charge exchange are evaluated by averaging over 10 orientations of the H2O molecule....
